The 3AXD50000940806 is an ABB ACH531-01-018A-4+X1663 LV AC wall-mounted drive sized for a 7.5 kW motor on 380-480 V three-phase supply. Normal-use output current is 17 A; light-overload use drops to 16.2 A at the same power rating.
The 7.5 kW normal-use rating and 17 A output current define the motor match for constant-torque HVAC loads like fans and pumps. Light-overload capability at 16.2 A covers the same motor class with a slightly lower current ceiling — useful when the load profile is steady and the drive runs below its full thermal limit. IE2 efficiency meets the current minimum for many regions, though IE3 or IE4 motors may require a different drive tier.
